    Description

      It would be nice to add a feature to MaxScale that could rebuild a corrupted machine or automatically build a new replica. That replica should then automatically join an existing cluster. This could be accomplished in a similar method that is used with Galera SST.

      On the current master:

      1. Launch MariaBackup
      2. Create a streaming snapshot of the datadir using xbstream/mbstream
      3. Compress with a utility like pigz for minimal transfer time
      4. Stream to the joiner/replica server with socat.

      On the joining node:

      1. Receive the socat stream
      2. Decompress
      3. Prepare MariaBackup
      4. Find the GTID position
      5. Register with the existing master / MaxScale
      6. Start slave replication
